Information comment
This comment provides useful information about this package. Make sure to read it through, you won't regret it.

Repository URL
This package is hosted at sos!git. If you want to contribute to the package, you can do it here: https://git.staropensource.de/JeremyStarTM/aur-linux-clear

Issue handling
Please only submit issues in the package's repository if they aren't bug reports about the package or help requests. Please keep them to the AUR only. This prevents unnecessary signups.

Updates
I usually publish updates 0-3 days after a kernel release, depending on how busy I am.
If I however get wind of security-relevant updates or any vulnerabilities I will try to update the kernel as soon as possible and write a comment about the vulnerability/update. So make sure to subscribe to this package's comment mailing list.

PKGBUILD environment variable customization
The PKGBUILD file supports customization via environment variables. Here's a list of all of them:
- _makemenuconfig: Invokes make menuconfig (ncurses-based default configuration menu) before compilation starts
- _makenconfig: Invokes make nconfig (ncurses-based nicer configuration menu) before compilation starts
- _makexconfig: Invokes make xconfig (X11-based GUI configuration menu) before compilation starts
- _use_current: Will use the configuration of the running kernel, if the running kernel is compiled with IKCONFIG_PROC
- _optimize_defconfig: Applies package maintainer-picked configuration changes to your defconfig. Only takes effect with _use_current being enabled
- _copyfinalconfig: Copies the final kernel configuration into the repository root as kconfig-new before compilation starts
- _localmodcfg: Only compiles modules found in modprobed-db's database (which decreases compilation time and kernel size)
- _use_llvm_lto: Compiles the kernel with LLVM instead of GCC. Should work, if not open an issue
- _subarch: Specifies the subarchitecture to compile for (see the PKGBUILD file for a list of all subarches). Default is 41/MGENERIC_CPU (Generic x86-64), which is compatible with all amd64 processors. Must be a number or subarch name
- _subarch_microarch: Specifies the microarchitecture to compile for. Only applies to and is required by the MGENERIC_CPU subarch. Must be a number between 1 and 4 (click for more information)
- _debug: Force enables debug options when set to y, force disables debug options when set to n or uses the config defaults when unset
- _show_compile: Enables verbose-er compilation output and displays all executing make targets

All of these variables just need to be set for them to apply, except for _subarch and _debug. For more information please check their documentation inside the PKGBUILD file

GPG errors
If makepkg complains about invalid PGP keys, try running this command first: gpg --locate-keys torvalds@kernel.org gregkh@kernel.org sashal@kernel.org benh@debian.org. This command only needs to be executed once.

Build tool
If you want a dead simple way to compile this package, you can try out my build tool. It includes a few no nonsense changes to the kernel configuration and allows you to configure the PKGBUILD file in a simple manner and decrease build time. And if you don't want that, using makepkg as-is works fine too.

I was wrong, i915/tgl_dmc_ver2_08.bin is not GUC but for power management, nevertheless also GUC seems not work.

With the default kernel all works well:

17/09/21 13:18 i915 0000 0:02.0: [drm] Finished loading DMC firmware i915/tgl_dmc_ver2_08.bin (v2.8) 17/09/21 13:18 i915 0000 0:02.0: [drm] GuC firmware i915/tgl_guc_49.0.1.bin version 49.0 submission:disabled 17/09/21 13:18 i915 0000 0:02.0: [drm] HuC firmware i915/tgl_huc_7.5.0.bin version 7.5 authenticated:yes

@metak: yes, it works well with the standard kernel but not for linux-clear

@guiodic Have you checked/tried what's in wiki? https://wiki.archlinux.org/title/intel_graphics#Enable_GuC_/_HuC_firmware_loading

17/09/21 12:40 kernel i915 0000:00:02.0: Direct firmware load for i915/tgl_dmc_ver2_08.bin failed with error -2 17/09/21 12:40 kernel i915 0000:00:02.0: [drm] Failed to load DMC firmware i915/tgl_dmc_ver2_08.bin.

I receive an error on Intel GPU firmware loading (GUC)

Direct firmware load for i915/tgl_dmc_ver2_08.bin failed with error -2

this make me unable to VP9 encoding via LibVa

@Tjuh It's optimized for intel hardware, but it should also work for AMD. Haven't tried it on amd.

Is this kernel mainly suited for Intel cpus or does it provide the same benefits for an AMD Ryzen 7 laptop?

For those unfamiliar with CFLAGs/-march optimizations

> https://wiki.gentoo.org/wiki/Safe_CFLAGS

Info on what option to choose, the differences, etc..

tl;dr -march=native is usually ideal

==> ERROR: Failure while downloading https://github.com/graysky2/kernel_compiler_patch/archive/20210817.tar.gz How to solve?

@xawiw Previously I removed that build parameter from PKGBUILD file because the proper way is to set it with MAKEFLAGS in /etc/makepkg.conf.

@Dobbie03 If you don't want native optimizations then choose skylake.
